<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I find that excuse somewhat weak. Sure, Qt's way of scaling is biting now, but that's <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">becasue</em> plasma had to make it's own way of scaling. Sure, i know the reasons why it was done and it was the best choice back then, but from day 1 it was known to become an issue if Qt was also going to support scaling. Which it obviously did since it has to keep up with modern day standards.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Plasma now is in the weird position where it needs to either adapt it's scaling to not conflict with Qt or throw all the custom scaling code away and start using the Qt way. Neither is easy imho.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">In later Qt we should have a way to say "I'll do my own scaling kthnxbye" <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">per window</em>, which I think is the ultimate long term solution.</p></pre>

There is not that much time to investigate and fix all of those properly before 5.4. Using Plasma without QT_DEVICE_PIXEL_RATIO currently gives great results on hidpi (running it myself), so I do believe that it is better to temporarily disable it for the 5.4 release and revert once those issues are gone.</p></pre>
